A US woman who shot and killed her husband and two adult children before taking her own life is thought to have committed the shocking crime as a result of being ostracised from the religion she was raised in.

A federal judge sentenced a former Arkansas judge Wednesday to five years in prison — a stiffer punishment than prosecutors recommended — after he admitted giving young male defendants lighter sentences in return for personal benefits that included sexual favours.

In a 60 Minutes online exclusive, reporter Liz Hayes quizzed Australian Prime Minister Malcolm Turnbull on his relationship with the unpredictable Twitter aficionado and US president Donald Trump ahead of their meeting at the White House Friday.

Mr Campbell, who also attended the school as a student, said he was never given an answer by the school about whether his sexuality posed a problem to his employment.

However, he later found out from his former colleagues that his name had been dropped from the list of the approved teachers.

South Coast Baptist College principal Des Mitchell confirmed to The West Australian that Mr Campbell was no longer working as a casual teacher for the school.

The school was on a “respectful journey of understanding” on the issue, Mr Mitchell said.

But he said gay relationships went against the school community’s foundational beliefs.

“Young people are naturally inquisitive,” Mr Mitchell said. “The image he posted created interest in his personal life, including his sexuality. I shared with him that, at present, there is an inconsistency with his beliefs on sexuality and the college’s beliefs,” he said.

A loophole in the WA Anti-Discrimination Act means it is legal for private or religious schools to sack gay staff members without needing to provide a reason why.

Similar loopholes also apply in other Australian states including NSW, Queensland and Victoria.
